Porsche has just released more official information about its upcoming 918 Spyder hybrid sports car, which is set to go into production at the end of 2013. Porsche is currently testing prototypes of the 918 Spyder, but has provided a glimpse of the prototypes, which hark back to the historical Porsche 917 racing cars. With more than 770 horsepower on tap and an estimated to 78 mpg fuel economy rating, this will be one hybrid that can’t be ignored.

The 918 Spyder is powered 4.6-liter V-8 engine and two independent electric motors. The V8 and one of the electric motors powers the rear wheels, while the second electric motor will send its power exclusively to the front wheels. The total output of the plug-in hybrid system will be more than 770 horsepower, but even with all that power on tap, the 918 Spyder will return up to 78 mpg (U.S.) The hybrid also is expected to have an electric-only range of around 15 miles. Porsche expects the 918 Spyder will be able to reach 0-60 mph in under 3.0 seconds with a top speed over 200 mph.

“What we are doing with the 918 Spyder is redefining driving fun, efficiency and performance,” said Wolfgang Hatz, Member of the Executive Board Research and Development of Porsche AG.

Deliveries of the Porsche 918 Spyder will commence before the end of 2013.
